JAR.

SPECIFICA'IION forming part of Letters Patent No. 634,742, dated October1 0, 1899.

Application filed April 19, 1899.

To all whom it may concern.-

Be it known that I, WALTER S. BAYLEss, a citizen ofthe United States,residing at Aber deen, in the county of Har'ford and State ofMaryland,have invented certain new and useful Improvements in Jars; andI do declare the following to be a full, clear, and exact de: scriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The invention relates to jars, and more par ticularly to themanner inwhich the cover or top is secured in place. 7

The object of the invention is to provide simple and durable meanswhereby the cover may be easily and quickly secured to and removed fromthe top of the jar and when in place hermetically seal the jar.

Another object of the invention is to construct the jars so that theymay be stacked one upon the other, thus saving agreat deal of space instorage and transportation; and a further object is to strengthen thejar at certain points,

With these objects in view the invention consists in certain features ofconstruction. and combination of parts, which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure 1 is a perspective view ofmyimproved jar. Fig. 2 is a longitudinal sectional view. Fig. 3 is a topplan view of the jar with the cover removed therefrom. Figwat is a sideelevation of the cover. i

In the drawings, 1 denotes the jar, preferably provided with an archedbottom 2 to add to its strength and at each end with an annular head 3,which in packing the jars prevent the sides of the jars coming togetherand breaking. The mouth of the jar is provided with an annular shoulder4, having segmental slots or recesses 5.

6 denotes the cover, which is provided with an annulardownwardly-extending collar 7, havinglaterall y-projectin g flanges8,provided with inclined upper edges and of. a length corresponding tothe length of the slots or recesses in the annular shoulder of the jar.

In sealing the jar the cover or cap is placed over the open end of thejar, with its flanges opposite the slots or recesses in the jar. Thecover is now forced downward and is given Serial No. 713,599. (Nomodel.)

a quarter-turn, which brings the flanges of the cover under the annularshoulder of the jar, and owing to the inclined upper faces of theflanges of the cover the said cover is drawn tightly downward upon apacking-ring 9, which may be placed upon the upper face of the annularshoulder.

The cover may be provided with any suitable means to enable its removal.As shown in the drawings this means consists of studs 10, which areadapted to be engaged by a wrench in the act of screwing or unscrewingthe cover.

It will be noticed that when the cover is in locked position on the jarits upper surface,

as well as the studs, occupies a plane below the annular head at theupper end of the jar, so that one jarmay be readily stacked upon theother.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages ofthe device will be readily understood without requiring an extendedexplanation.

The device is exceedingly simple, may be made at small cost, and is welladapted for the purpose for which it is designed.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

A jar of the character described provided with an arched bottom and withannular beads at its upper and lower ends and on its external side, saidjar having an internal laterally-projecting flange near its upper end,said flange being provided with opposite recesses; in combination with acover having an annular flange between which and the internal flange ofthe jar a packing is adapted to be clamped, said cover having near itslower end laterally-proj ecting flanges having inclined faces adapted toengage the under side of the internal flange of the jar, and said coverwhen in position being below the upper end of the jar, substantially asand for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. 7
